      <title>CVE-2022-49508 — HID: elan: Fix potential double free in elan_input_configured</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2022-49508</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Linux&lt;/p&gt;
&lt;p&gt;In the Linux kernel, the following vulnerability has been resolved:&lt;/p&gt;
&lt;p&gt;HID: elan: Fix potential double free in elan_input_configured&lt;/p&gt;
&lt;p&gt;&amp;#39;input&amp;#39; is a managed resource allocated with devm_input_allocate_device(),
so there is no need to call input_free_device() explicitly or
there will be a double free.&lt;/p&gt;
&lt;p&gt;According to the doc of devm_input_allocate_device():
 * Managed input devices do not need to be explicitly unregistered or
 * freed as it will be done automatically when owner device unbinds from
 * its driver (or binding fails).&lt;/p&gt;</description>
